Tekken Card Tournament was downloaded over a million times (in aggregate) within the first four days of its availability on the App Store, Google Play and Amazon's Appstore for Android, Namco Bandai has announced. That's not counting however many people played the game directly in their browser, either.
To signify the occasion, Namco Bandai has enacted a 48 hour, 30 percent off sale for all in-game booster packs, as of 11 a.m. Eastern this morning. Do note: this discount applies to the packs of cards themselves, which must be purchased using in-game currency. The purchase price of the in-game currency itself, however, has not been discounted, though you'll still get more for your credits while the sale is in effect.
You can always earn credits by winning matches and stuff too, but who has time for that in this modern age?
